At Project ZeroF, safe and sustainable coatings are being developed to replace PFAS compounds in the value chain of food packaging and cushioning textiles.

Packaging made of paper and plastic are everyday companions through their use for food, medicines or cosmetic products.
The list of specifications related to their functional properties became longer and more severe over the past decades.
The Fraunhofer ISC has many years of experience in the development of functional layers for paper and plastic packaging to meet individual customer requirements.
With the help of a extensive network of partners, we also help companies to design and implement innovative environmentally friendly packaging for a wide range of products and accompany them until they are ready for the market.
We help with support on the possible choice and combination of materials and adapt our coatings so that special requirement profiles matched exactly. Minimum shelf life can thus be guaranteed without oversizing packaging. This is made possible by our highly functional ORMOCER®/bioORMOCER® coating materials, which can combine different properties in one layer:
Films as well as three-dimensional geometries can be upgraded with our very thin functional layers (< 1 µm - 3 µm) using state-of-the-art application processes. This enables us to produce biodegradable or easily recyclable packaging.
Here you will find our contribution to modern environmentally friendly packaging:
Conventional packaging films are high-performance products - but unfortunately hardly recyclable. Our transparent multifunctional barrier coating combines many packaging functions in 1 to 3 µm and adheres very well to plastics or paper. This makes it possible to create a so-called monofilm for easily recyclable packaging. This barrier concept can also be transferred to complex geometries for rigid packaging.

We have also developed special barrier concepts for paper and board based materials:
Our barrier layers now enable packaging solutions made of paper or cardboard with properties close to those of plastic packaging. In addition, the packaging can also be made completely compostable with the bioORMOCER® option.

To make packaging materials more environmentally friendly, barrier layers must also become bio-based and biodegradable.
With its newly developed bioORMOCER® coatings, the Fraunhofer ISC can significantly improve the barrier performance of conventional bio-packaging.
Through inorganic-organic material combinations, properties can be specifically optimized and adapted to the product.
In addition to the "basics", we can also equip packaging with "smart" functions. These include active functions such as oxygen scavengers, UV protection or counterfeit protection, as well as many sensory functions that we incorporate by means of molecules and/or particles. For example, in the case of exposure to gases (oxygen, CO, etc.) or heat (interruption of the cold chain), mechanical influences (e.g. impact) and other undesirable influences can be integrated directly into the packaging material as a sensory function.
We have also developed modern solutions for the glueing and later simple separation of packaging in recycling.
